A transfer fee covenant recorded in this State on or after the effective date of this Act shall not run with the title to real property and is not binding on or enforceable at law or in equity against any subsequent owner, purchaser, or mortgagee of any interest in real property as an equitable servitude or otherwise. Any lien purporting to secure the payment of a transfer fee under a transfer fee covenant recorded in this State on or after the effective date of this Act is void and unenforceable. This Section does not mean that a transfer fee covenant or lien recorded in this State before the effective date of this Act is presumed valid and enforceable.
